Abstract: A centralized gateway server receives a first user request, configured to operate with a first development platform, indicating a first operation to be performed on behalf of a first user. The centralized gateway server generates a first service request for performing the first operation, and transmits the first service request to a server associated with a service, to cause the server to perform the first operation on behalf of the first user. The centralized gateway server also receives a second user request indicating a second operation. The second user request is configured to operate with a second development platform different from the first development platform. The centralized gateway server generates a second service request for performing the second operation, and transmits the second service request to the server to cause the server to perform the second operation.

Abstract: An activation code to be provided to a cardholder associated with a payment card is generated. The activation code is an electronically scannable code that encodes payment card information associated with the payment card. The activation code is subsequently received from a user device, the activation code having been electronically scanned by the user device. The payment card information, associated with the payment card, is extracted from the activation code received from the user device. Activation of the payment card is performed using the payment card information extracted from the activation code received from the user device.
